Cloudflare Worker Previews: Per-Branch Environments for Workers
Summary
Cloudflare introduced Worker Previews, which gives each Git branch an isolated, production-like environment for a Worker. The feature creates stable URLs, branch-specific configuration, and scoped observability so teams can test changes without affecting production traffic. Cloudflare built it to support agent-driven development, where frequent large code changes need fast feedback loops. The release is available now after a private beta, though some limitations remain for multi-Worker apps, queues, and workflows.
